T0 all 'LU/1.0m t may concer-a:

Be it known that l, HERMANN Henneman, a citizen of the Republic ofSwitzerland, residing at iVetZikon, Canton Zurich, Switzerland, haveinvented an improvement in Spindles for Textile Machinery, of which thefollowing description, in connection with the accompanying drawings, isa specification, like characters on the drawings representing likeparts.

rlhe present invention relates to improvements in spindles for textilemachinery.

Spindles for spinning and twisting machines are known in whichanti-friction bodies, such as balls, rollers and the like, are arrangedin a driven cage and are revolved thereby about the axis of the spindie.As the anti-friction bodies rest against the stationary sleeve andagainst the blade of the spindle they are rotated in addition ot beingrevolved and cause thereby the rotation of the blade at a speed which isdifferent to the speed at which the bearing caOe is rotated for instanceby the whirl.

ith the hitherto known spindles of this type the blade has beensupported by a thrust bearing which is disadvantageous in many ways. lncontradistinction thereto with the spindle according to the presentinvention the anti-friction bodies are rotatably and non-displaceablymounted in the driven cage and rest against the blade and against thesleeve, the blade having at least one conical portion held in positionby said antifriction bodies without the use of a thrust bearing. Y

Several embodiments of the subject matter of the invention areillustrated on the accompanying drawing showing vertical spindles.

n the drawings- Fig. 1 shows in a vertical section a firstconstructional example,

Fig. 2 is a detail of Fig. 1 developed in a plane,

Fig. 3 is a vertical section through a second constructional example, Y

Fig.- l is a vertical section through a third constructional example,

5 is a vertical section through a fourth constructional example and Fig.6 is a detail modification.

Referring now to the first constructional example illustrated in Figs. 1and 2, 1 denotes the whirl driven by the usual cord lll,

Serial No. 751,561.

Jabove the whirl 1 a cap 9. is provided integral with the whirl and abush-shaped cage 3 is screwed into the cap 2, so that whirl 1 and cage 3are rigidly connected to each other. ln the cage 8 rows of balls 6 arearranged, two rows are provided in the upper part and two rows in thelower part of the cage. In the cage 3 the lower conical part of theblade 7 is loosely inserted and held in position by the balls 6. rEhecage 3 is surrounded by the sleeve 8 which adjusts itself in the lateraldirection when the spinn die is working; the bore of the sleeve 8 tapersdown towards its lower end. A spring 9 secures the sleeve 8 within thestationary bush 10 against rotation without impairing the lateraladjustability of the sleeve 8. The bush 10 is screwed to the rail 11 ofthe textile machinery. rlhe upper edge 12 of the outer bush 10 projectsloosely into an annular groove 13 provided in the lower end of thewhirl 1. Balls 6 of such a diameter are chosen and the mounting of theballs is so arranged that the latter rest against the blade 7 as well asagainst the interior surface of the sleeve 8. The downward taper ofthese two parts causes the balls 6 to firmly rest against their racesurfaces. 'lhe balls 6 are the sole means for mounting the blade 7, thelatter is pressed by its own weight against the balls and is supportedby the latter. rlhereby the balls 6 act as driving means interposedbetween the shaft 7 and the whirl 1 and transmit the rotary movement ofthe whirl 1, imparted to the latter by the cord 14, and of the cage 3revolving with the whirl to the blade 7. The ratio between the speed ofthe whirl 1 and the speed of the blade 7 can be chosen at will bychoosing the diameters of the balls and the ratio between the diametersof the inner and the outer surfaces on which the balls roll, i. e. thediameter of the blade and the bore of the sleeve. The balls act thus asthe means for raising the speed of the blade 7 as compared with that ofthe driving member or whirl 1. rlhe degree of the taper of the bore inthe sleeve 8 and of the blade 7 and the diameter of the antifrictionbodies 6 is preferably so adjusted relatively to each other that in allthe places where the movement of the sleeve 8 is transmitted to theblade 7 the same transmission ratio is present so that no slippingmovement but solely a rolling movement of the balls 6 on the surfaceswith which they cooperate occurs. lf the spindleis only slightly raisedit is no longer driven and remains at a stand- "il whilst the whirl ltogether with the cage continues to rotate. 'llhc balls 6 rotate aboutaxes which are approximately parallel. to the airis of the blade 7. itsis shown in lfinj. 2, the apertures l5 of the cage 3 in which. the balls6 are inserted are, for instance, so shaped that the extension of theapertures at right angles to the axis of blade is larger than the eX-tension in the direction of that axis. Thereby the friction of the ballsin the cage during' their rotation is reduced as much as possible. rlheballs bear against the cage in their poles, that is to say at points inwhich the circumferential velocity is a minimum or, theoretically,equals to zero.

lilith the constructional example illustrs-,ted in Fig. 7 denotes theblade, 3 is the ball bearing cage and G are the balls. ln this examplethe cage is prov'ded with eX terior thread 16 with which the worin wheel17 cooperates. The balls 6 rest against the conical blade 7 and against'the laterally movable sleeve S, which is secured against rotation bymeans of a spring 9 bearingl against the stationary bush l0, the latterbeing provided with an extension l0" cnclosing the worm wheel 17.

1With the third constructional example sliow'n in Fig'. l it is assumedthat the worin wheel 17 rotates in a direction which is opposite to thedirection in which the worm wheel 17 in Fig. 3 revolves, the respectivedirections of rotation being); indicated by arrows. In order to take upthe axial thrust acting in the upward direction and occasioned by theworin wheel cooperating with the worm a ball thrust bearing,y 1 8 isprovided, Also in this example the lateral moi/'ability of the sleeve 8is ensured and the blade is supported by the balls 6 resting on theconical bore of the sleeve 8 and against the blade 7.

ln the embodiment of the invention shown in Fig 5 the bore of the sleeveS is cylindrical and the blade 7 is composed of a plurality of conicalportions 7, each such portion serving as the interior race of a row ofballs 6. The cage 3 is supported by a thrust bearing 19; the blade 7,however, is solely supported by the balls G.

instead of balls other anti-friction oc-dies may be utilized. ln Fig. 6in which onlyY the top portion of the spindle is shown, theanti-friction bodies consist of conica-l rollers 6a fluted at theircircumference and resting` against a correspondingly fluted conical part7b of the blade and aaa-inst a fluted portion Sa of the sleeve 8. Theremaining structure is similar to that illustrated in Fig. l.

The aforedescribed spindles present the advantage that the blade isloosely supported, it floats, so that any wear which may taire placedoes not impair the driving connect-ion.
